Access Control is a security measure that ensures only authorized individuals are able to access resources. This can include physical spaces, such as buildings or areas within a building, as well as digital resources, like computers and networks. Access Control systems typically require users to authenticate themselves before they are granted access using methods like passwords, tokens, or biometrics. These systems help protect important assets from unauthorized use by limiting the amount of people who can gain access to them. Access Control is an essential part of any security system and should be implemented wherever critical information or resources need to be safeguarded.
